Foley, St. John County, New Brunswick, Canada Application April 19, 1935, Serial No. 17,294 In Canada April 21, 1934 2 Claims.

This invention relates to molds for the manufacture of teapots and similar vessels equipped with tubular pouring spouts. Its principal object is the provision of a sectional mold in which a 5 seamless spout may be cast in one piece with the body of a vessel without interfering with subsequent separation of the vessel from the mold sections.

The usual teapot mold in which the spout and body are cast in one piece is divided into half sections meeting in a vertical plane bisecting the body and spout forming portions of the mold. With this type of mold iins are formed on the spout and body of the teapot along the vertical meeting faces oi the mold sections. Owing to their direction and location, these fms cannot be conveniently turned down in a lathe and are usually removed by a hand operation which requires considerable time and skill in order to avoid breakage, especially in the case of the comparatively fragile pouring spout. Moreover, it is frequently impossible to remove these fins without leaving some semblance of seam lines which tend to mar the appearance of the finished vessel. It is also common practice to cast the body of a teapot in a mold divided horizontally but, in this case, the spout is cast separately and then joined to the body by a separate operation.

According to the present invention the mold is divided horizontally into upper and lower sections. The side Wall of the upper section is provided with a curved tubular cavity in which the spout of the teapot is cast in one piece with the upper portion of the body. The curvature of the spout forming cavity is such that the upper mold section is easily separated from the spout and body portion of the teapot by raising said section with a circular motion so that it travels in a curved path about a centre corresponding to the centre of curvature of the bottom wall of the spout forming cavity. With this type of mold the circular iin formed on the body of the teapot along the horizontal meeting edges of the mold sections may be easily and quickly turned down in a machine similar to a lathe. It will thus be seen thatthe mold of the present invention not only eliminates the formation of ns on the spo-ut but also enables the n formed on the body of the teapot to be very easily and quickly removed so that the entire process of manufacture is speeded up in considerable degree.

Proceeding now to a more detailed description, reference will be had to the accompanying drawing wherein- Fig. 1 is a vertical sectional View of my improved mold showing the manner in which the seamless spout is cast in one piece with the body of a teapot.

Fig. 2 is a View similar to Fig. 1 but showing 5 the upper mold section and the teapot lifted out of engagement with the lower mold section.

Fig. 3 is a vertical Sectio-nal view illustrating the manner in which the upper mold section is separated from the spout and body of the l0 teapot.

As shown in the drawing, my improved mold is divided horizontally into upper and lower sections designated 5 and 6. These sections are provided with stepped meeting edges 5a and 6a 15 to hold them against relative lateral movement in their assembled relation. In addition to its main cavity the upper section 5 is provided with the usual groove l in which an upwardly projecting rim 8 is cast in one piece with the upper 20 part of the teapot body 9, in which the usual filling opening Ill is formed. Section 5 is also provided with a thickened side wall pierced by a tubular opening or spout forming cavity l! in which the spout l2 of the teapot is cast, with- 25 out seam, in one piece with the upper portion of the body 9. The top and bottom wall portions of the spout forming cavity H are curved as clearly shown in the drawing, the centre of curvature being located approximately at the point marked X in Figs. 1 and 2, While the exact location of the point X is subject to some variation it is usually located in the plane Y at a distance in front of the mold equal to approximately one-half of the circumference of the pot at the level represented by said plane.

Upon completion of the casting and drying operations, the upper mold section 5 and the teapot are raised out of engagement with the lower mold section 6, as shown to advantage in 40 Figure 2. The mold section 5 is then removed, as shown in Figure 3, by lifting it with a circular motion centering about the point X which is also the centre of curvature of the bottom wall portion of the spout forming cavity Il. It would 45 seem that the teapot rim 8 would interfere with the aforesaid circular movement of the mold section 5 but, in practice, it happens that the shrinkage incident to the drying of the clay from which the teapot is made provides suii'icient 50 clearance to permit the desired movement of the mold section. At the meeting point of the mold sections 5 and 6' a circular iin is formed around the teapot body 9 but this fin, being concentric 55 with the body, may be easily and quickly turned down in a, finishing machine similar to a lathe.

Having thus described my invention, What I claim is:-

1. A teapot mold divided horizontally into upper and lower sections, the wall of the upper section being pierced by a tubular spout forming cavity bounded by said wall.

2. A mold divided horizontally into upper and lower sections, the wall of the upper section being pierced by a tubular spout forming opening or cavity curving upwardly and forwardly from the main mold cavity, the centre of curva.- ture of said opening or cavity being located at a predetermined point in front of the mold so that the upper mold section, when raised with a circular motion centering at its point, may be disengaged from the spout and body of the teapot.
